AULINK Camshaft Position Actuator Solenoid Kit for 2.0L & 2.5L GM Engines — Intake & Exhaust Pair with Improved Seals

These AULINK intake and exhaust camshaft position actuator (VVT) solenoids replace OE numbers 12655433 and 12655434 to restore proper variable valve timing control on compatible 2.0L and 2.5L GM engines.

If your vehicle shows VVT-related trouble codes, rough idle, or reduced performance, worn or leaking camshaft position actuator solenoids are a common cause. AULINK supplies a matched intake and exhaust solenoid set engineered to meet factory fitment and timing control requirements for a range of Buick, Cadillac, Chevrolet, GMC, and Buick models. Each unit is produced in a TS16949 certified facility and includes improved sealing to reduce oil leakage and maintain consistent oil flow to the VVT system.

How will these solenoids affect engine timing and drivability?

These solenoids regulate oil flow to the cam phasers so the engine computer can advance or retard camshaft position as needed. When functioning correctly, they help the engine reach designed combustion timing, improving idle stability and throttle response. Faulty solenoids can cause erratic timing, triggering warning lights and limp-home behavior.

• Matches OE control function for intake and exhaust circuits
• Improved O-rings reduce the risk of premature oil leakage
• Helps maintain consistent oil pressure to the VVT phasers

How difficult is installation and what should I check?

Installation is a moderate DIY job for someone comfortable with basic engine work: it usually requires removing an engine cover and electrical connectors, then swapping the solenoids. Clean the mounting bores and inspect wiring harness connectors for corrosion before installing new parts. If in doubt, a professional mechanic can complete the replacement and clear any stored codes.

• Requires basic hand tools and possibly a scan tool to clear codes
• Clean O-ring grooves and apply engine oil to new seals before fitting
• Verify part numbers and orientation during installation

Who is this for: This AULINK intake and exhaust VVT solenoid kit is aimed at owners and technicians working on affected GM 2.0L and 2.5L engines who need a reliable, OE-replacement solution. Choose this kit if you require direct-fit parts that restore variable valve timing control, reduce oil leaks at the solenoid interface, and come with factory-level quality checks and a limited warranty.
